| Research Abstract |
The Telescope Array experiment has been measuring air fluorescence lights emitted from extensive air showers(EASs) produced by ultra high energy cosmic rays. Since atmospheric condition affects measurement accuracies of EAS, atmospheric monitoring is important. For the atmospheric monitoring, cloud monitors equipped CCD cameras with fisheye-lens were developed, and were installed at the top of buildings of the fluorescence light detector. In the first 2 years operation, availability ratio of 99% was achieved. This ratio will be been keeping beyond the end of this budget. We studied a cloud finding algorithm from obtained pictures.
